Calculate the LCM of 411,474,424,420

Given numbers are 411,474,424,420

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 411,474,424,420 is 481839960.

Find LCM of 411,474,424,420 with Prime Factorization


2 411, 474, 424, 420
2 411, 237, 212, 210
3 411, 237, 106, 105
137, 79, 106, 35

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 137 x 79 x 106 x 35 = 481839960

Therefore, the lowest common multiple of 411,474,424,420 is 481839960.

LCM Formula to Find Lowest Common Multiple of 411,474,424,420

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

411 x 474 x 424 x 420 = 34692477120

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

411 : 1, 3, 137, 411

474 : 1, 2, 3, 6, 79, 158, 237, 474

424 : 1, 2, 4, 8, 53, 106, 212, 424

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,474,424,420, is 1.

Now, the common factors can be found like this.

411:3x 137

474:2x 3x 79

424:2x 2x 2x 53

420:2x 2x 3x 5x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 3 = 72

Therefore, the value for common factors is 72.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 34692477120/(1x72)

LCM = 34692477120/72

LCM = 481839960

Thus, we can understand that the LCM of 411,474,424,420 is 481839960.
